As of Django 1.8.16, Django is rejecting any HTTP_HOST header that is
not on the ALLOWED_HOST list.  We often need to reference the
toaster server via a fqdn, if we start it via webport= for
instance, and are hitting the server from a laptop. This change does
reduce  the protection from a DNS rebinding attack, however, if you are
running the toaster server outside a protected network, you should be
using the production instance.

Fixes [YOCTO #10578 ].

+# To have that same behavior, with a fqdn explicitly enabled you would set

+# Django >= 1.8.16. By default, we are not enforcing this restriction in
